DDR Memory Support
Certain PICs on the right edge of MachXO2-640U, MachXO2-1200/U and larger devices, have additional circuitry
to allow the implementation of DDR memory interfaces. There are two groups of 14 or 12 PIOs each on the right
edge with additional circuitry to implement DDR memory interfaces. This capability allows the implementation of up
to 16-bit wide memory interfaces. One PIO from each group contains a control element, the DQS Read/Write
